Made for assembly line, machine automation, and other applications, this RoHS-compliant wide gap optical sensor includes an emitter-sensor pair. Its LED and phototransistor are made to work over up to 12 inches in industrial environments. The sensor components are mounted in threaded color-coded housings. The emitter-sensor pair uses an LED with a 935 mm peak wavelength and a silicon phototransistor. The pair will mate with a Molex 03-06-2023 connector with either male (for the LED) or female (for the sensor) pins. The output phototransistor performs at collector-emitter voltages of 30V, emitter-collector voltage of 5V, and power dissipation of 100 mW. The LED has a maximum continuous forward dc current of 40 mA, a reverse voltage of 2V, and power dissipation of 100 mW.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
